I am with Derek in this case, but remember that 192.168.n.n, 10.n.n.n
and 172.16 - 172.31 are non-routable meaning that your router SHOULD
never expose these addresses beyond the subnet. So, in the case where
you have to set something up at the last minute, the 192.168 addresses
are not going to conflict. I would also make sure that the wifi is set
up with a pass code so that people outside the group can't use it
although in this case the risk is minimal. especially if you disconnect
the router after the boy scout meeting.
